    mtd: dataflash: Export OF module alias information
    
    The SPI core currently reports the MODALIAS uevent as "spi:<modalias>"
    even for SPI devices that were registered by OF.
    
    That means the OF module alias exported by MODULE_OF_TABLE(of,...) is
    currently not used and user-space has no way to autoload this module.
    
    But it is still a good practice to add the OF module alias information
    into the kernel module even when it currently is unused so once the SPI
    core is changed to report a correct OF modalias uevent, module
    autoloading will be working for this driver.
